Good question.  That was the old BSD behaviour, but was later changed
by some reason I don't know.  It would be the for sure simplest 
solution (adding one line of code).

RFC826 suggests that new arp requests should be sent before the
old arp entry is deleted, therefore I gave this as an example 
of a solution to the problem.  Which solution does not matter to 
me, only that the problem must be solved.
